Abstract / Description of output

Studies indicate that mito-genome variation impacts phenotypes in a range of species. In dairy cattle up to 5% of phenotypic variation for milk production has been associated to mito-genome variation. Bearing in mind that milk production is a very energy demanding process that inflicts systemic physiological changes, it is logical to expect that it depends on well-functioning mitochondria. Here we evaluated the impact of accounting for nuclear- and mito-genome variation in genetic evaluation and breeding of dairy cattle with the means of stochastic simulations. Results show that accounting for mito-genome variation can increase the accuracy of estimated breeding values by up to 0.04, particularly in females, and consequently increase genetic gain.
